fix Invalid DNS Zone caused by tailing newline characters

[jm-x1n09]

It took me several hours to debug Invalid DNS Zone exception, and finally I realized that multi-line command in PowerShell attached a newline character to the value of --azure-dns-zone.

(It was the line --azure-dns-zone /subscriptions/********-****-****-****-************/resourceGroups/***/providers/Microsoft.Network/dnszones/***.com` that involves newline to option.DnsZoneResourceId

./az-acme.exe order `

>>         --key-vault-uri https://***.vault.azure.net/ `
>>         --certificate ***-acme-certificate `
>>         --subject "***.com" `
>>         --sans "1.***.com" `
>>         --account-secret ***-amce-registration `
>>         --dns-provider Azure `
>>         --azure-dns-zone /subscriptions/********-****-****-****-************/resourceGroups/***/providers/Microsoft.Network/dnszones/***.com` ###
>>         --renew-within-days 180 `
>>         --verbose
